Systolic and diastolic functio... |
22,287 | The short-long-short-short sequence and polymorphic ventricular tachycardias storm. | We described a case of a patient who developed repetitive episodes of polymorphic ventricular tachycardias with a stereotypical pattern of initiation. A short-long-short-short (S-L-S-S) cardiac cycle sequence preceded all episodes and was considered to be the underlying initiative mechanism for these fatal arrhythmic e... |

However, the effectiveness of catheter ablation (CA) for atrial functional TR together with the mechanisms of improvement of atrial functional TR have not been fully evaluated.</AbstractText>We retrospectively investigated c... |
22,289 | Blocking nerves and saving lives: Left stellate ganglion block for electrical storms. | Patients who present with electrical storms (ES) due to rapid recurrence of ventricular tachycardia/ventricular fibrillation represent major medical emergencies without easy solutions. Antiarrhythmic drugs have limited value, and ES need to be stopped quickly to prevent irreversible patient deterioration and death. Sin... |
22,290 | Evaluating Gender-based Differences in Clinical Outcomes for Patients Undergoing Left Atrial Appendage Occlusion: A Single Centre Experience. | There is emerging recent data that has shown women to be more prone to in-hospital major adverse events after trans catheter left atrial appendage occlusion. Institutional LAAO registry at West Virginia University (WVU) was reviewed from January 2016 to October 2021 to identify 271 women and 293 men who underwent succe... |
22,291 | Effects of temperature control on hyperthermia-related cardiac dysfunction in a porcine model of cardiac arrest. | The outcome of cardiac arrest is worse when there is fever after spontaneous circulation is restored (ROSC). The purpose of this study was to investigate the mechanism of post-ROSC cardiac dysfunction after hyperthermia treatment and the effects of temperature control. Twenty-four male Bama minipigs were randomized int... |
22,292 | Impact of Atrial Fibrillation on Outcomes in Very Severe Aortic Valve Stenosis. | The prevalence and impact of atrial fibrillation (AF) versus sinus rhythm (SR) on outcomes in very severe aortic stenosis (vsAS) of the native valve is unknown.

22,293 | Cardiopulmonary Exercise Testing in Athletes With Hypertrophic Cardiomyopathy. | Patients with hypertrophic cardiomyopathy (HCM) have historically been restricted from athletic participation because of the perceived risk of sudden cardiac death. More contemporary research has highlighted the relative safety of competitive athletics with HCM. However, lack of published data on reference values for c... |
